Valis: The Fantasm Soldier (夢幻戦士 ヴァリス Mugen Senshi: Varisu?, lit."Dream Soldier: Valis") is the first video game in the Valis series. Telenet Japan originally developed and published Valis in 1986 for the MSX and PC-88 home computers. Tokuma Shoten would later release a version for the Famicom in 1987. In 1991, additional publishers Riot (Japan) and Renovation (US) released versions for the Mega Drive (the Sega Genesis in North America). An enhanced remake of the Mega Drive version was also released for the PC Engine's Super CD-ROM². In 2005, Telnet released another remake of the game, this time for mobile phone platforms in Japan. The game spawned several sequels including Valis II, Valis III, Valis IV. The Valis series stars a Japanese schoolgirl named Yūko Asou (麻生 優子 Asou Yūko?), who uses a mystical sword called Valis to defend Earth, the spirit world and the dream world.
Valis: The Fantasm Soldier is a side-scrolling platformer. Wielding the game's titular sword, the main character fights through each level's enemies while jumping across ledges, then confronts a boss at the end of each level. At certain points in the game, gameplay pauses, and cinema scenes regarding the game's storyline play.
Like other side-scrolling games of the era, the four D-pad buttons move the character, and the three fire buttons perform three actions for the main character: sliding, jumping, and swinging her sword. The player can view a list of usable magic by pressing the Start button.
